---|---|---|
Current experience with anti-cancer medicines | Varied frequency of shortage | Some medicines get shot on daily basis, some of them on weekly basis and those medicines which have very low consumption, that are monthly or annually or biannually (Participant 7). |
Brand shortages | We experienced a bit of shortage of brands of chemo medicines after every two to three months (P11) | |
Shortages depends upon types of medicines | It depends upon type of drug effected, either it is first line drug, or second line drug or some targeted therapy (P25). | |
Impact of COVID-19 on shortages | COVID-19 aggravated the anti-cancer medicines shortages | In COVID-19, logistics are involved and major shortages happened. The import clearances of single brand/drug also take enough time. Drug is present at Pakistani port but not available to the patient. So before COVID-19, it was monthly but in COVID-19, it is daily or weekly (P8). |
COVID-19 led to an increase in the price of short medicines | Many wholesalers or distributors or manufacturers created artificial shortages to increase the rates and prices of medicines and sold them at black rates. It was all for monetary benefits (P4). | |
Ethical dilemma | Pharmacists have to prioritize the patients (First come, first get; Curative care patients will be preferred on the palliative care/dying one; Distant patients are preferred on nearer one; Poor are preferred on rich) | If we have started chemo of one patient, we have to ensure that patient must receive complete cycle of chemotherapy. We will never start to the new patient since we have to ensure first that those patients we have already, must complete their cycles (P1). |
Other professionals make the decision (Physicians, Multidisciplinary team meeting) | Basically, our hospital used to develop criteria in the multidisciplinary team meeting that included physicians, pharmacists, consultants, radiologists, and other professionals also. They basically developed a criteria for the best use of the shortage drug (P21). |

Regulatory issues | Compromised role of DRAP (In the aspects of registration, license renewal, import, price management and supply chain management) | One of the things is the challenging drug registration process, which is a very cumbersome process, it’s not a robust process. So, any new anti-cancer treatment which comes into the global options is very late registered within Pakistan (P13). |
The important cause is the DRAP, the authority is not working properly, unable to understand the issues. If DRAP will not work honestly, then everyone has to face issues of registration, import, expiry, and black market (P10). | ||
Lack of local production | These agents are not manufactured in Pakistan (P17). | |
Brand prescribing trend | Pharmaceutical companies attract physicians just to promote their brands and physician have to prescribe the particular brand (P3). | |
Suppliers/Distributors issues | Lack of local or international vendors | They are not much interested and dealing in anti-cancer where they have to invest capital and do precautions. Only a few dealers or wholesalers are dealing with anti-cancer drugs (P5). |
Increased contracts with hospitals than capacity | They took orders from so many hospitals and were unable to provide the expected stock which lead to a shortage (P2). | |
Short expiry drugs | If a drug has short expiry (as most anti-cancer drugs), then automatically, the drug has a short market time and delays caused by distributors may cause shortages and loss of drug (P10). | |
Unfair distribution | The focus of distributors/wholesalers is upon the big cities or big hospitals for more profit, and this also causes a shortage in remote areas or distant areas (P9). | |
Manufacturing issues | Raw material issues (high cost and unavailability) | The raw material is of very high cost now, that’s why they fail to get appropriate price and try to avoid manufacturing (P1). |
Quality concerns of locally production | ||
Hospital issues | Clerical issues | In government hospitals, there is purchasing committee involving admin, accounts and this takes a lot of time before going to purchase a drug leading to shortage (P9). |
Not involved | The hospital itself didn’t play that much role since they completely rely on the distributor, on the manufacturing somehow (P17). | |
Common causes among stakeholders | Lack of communication | There is a lack of communication among the oncology Society of Pakistan, drug regulatory authority of Pakistan, and the Ministry of Pakistan (P6). |
Artificial shortage | The main reason related to distributors and manufacturers, is they want their drug on high pricing, they increase their profit margins creating a fake shortage. Sometimes, they create a fake shortage to consume their short expiry bag (P3). | |
Inappropriate inventory management | Basically, distributors have not maintained their inventory as per the patient’s need or either they do not have sufficient data for arranging the store of medicine for particular timing. The same is the case with hospitals (P12). | |
Presence of a single supplier for a single drug | This is the most critical thing that we have one drug and one distributor, which is always alarming since if a distributor has some personal reason for the business and if he drops a sale or import, the impact comes on the country (P13). | |
Demand fluctuation and small market size | There are a certain number of institutions, which are just dealing with oncology. So it’s not a huge number that is prescribed by every second physician (P3). |

Clinical impact | Suboptimal treatment | When a patient does not get his medicine on time, it obviously deteriorates his health. There will be long hospitalization, there will be long-term timing of the treatment schedule and automatically there will be a sub-optimal health condition (P22). |
Delayed treatment | The process of importing is a little bit lengthy leading to delayed treatment (P13). | |
Adverse drug reactions | Adverse effects may occur using alternative/other therapies. This is due to the fact that in clinical settings, doctors choose the medicine on the basis of the patient profile, for example, a cardiotoxic adriamycin cannot be given to a cardiac patient but if the other choice is eliminated, it will go (P12). | |
Death | Every day delay leads to increase mortality (P5). | |
Financial impact | Increased out-of-pocket costs for the patient | Patients have to bear their traveling costs, emotional costs, they have to pay more, they have to pay if there is a shortage and they get medicine from another city and they have to administer in another city (P8). |
Impact on pharmacist | Increased workload | We have to sometimes spend our whole day figuring out how to counter the shortages (P14). |
Pharmacists become frustrated (Disturb pharmacist-patient relationship, accused of incompetency) | Our department and our higher authorities blame us that we have to meet our needs. So we are in a tightrope that we are pulled on both sides, from the one end by patients and from the other end by higher authorities (P22). |
Subthemes | Categories and Subcategories | Quotations |
---|---|---|
Proactive measure | Anticipated demand and shortages as well | We have an electronic inventory control system through which we can assess what are the actual needs of the institution, and how much smooth supplies do we have (P13). |
Procure more than one brand | Mostly we have approved two brands in our formulary. On the shortage of one, we go for the other (P8). | |
Shortened the procurement decision-makers | We shortened the procedure of purchasing drugs by shortening the decision-makers for purchasing (P25). | |
Counter active measure | Manage within hospital (Change the protocol, delayed the treatment, switch to alternatives, compounding) | Sometimes we have to switch to a therapeutic equivalence after a doctor’s consultation (P14). |
Manage within country (Contact other hospitals, arrange drugs from the black market, contacting multiple suppliers, patient arrange their own medicine) | First of all, when we faced a shortage of anti-cancer medicine, we contacted our friends from other institutes, So we contacted their departments, and then we contacted other pharmacies (P22). | |
Many times patients arrange their medicines. Sometimes those drugs are not available in hospitals or at the distributor level but are available on the black market for the patient so patients have to purchase (P12). | ||
Manage through import (Patient need base import, institution need base import) | One alternative way is to import the drug instead of waiting for the trial period. So the first thing is the integration. The second thing we go for is the patient need basis import process. The third thing we go for is the institutional import process to overcome such drug shortages (P13). |
Subthemes | Categories and Subcategories | Quotations |
---|---|---|
Regulators | Introduce updated policies (Policies for registration/import/license renewal/fix prices/profit margin/drug supply chain management/those who break the law) | DRAP authorities should update regulations on which they have to allow the timely import of medicines. DRAP should also counter-check drug registration and license renewal policies to make the process smooth (P14). |
There must be penalties for those who break the laws and hold the medicines for the sake of profits, those who produce artificial shortages, and those who sell drugs at higher prices (P4). | ||
Financial support to stakeholders (Register reputable manufacturers for local manufacturing, contracts with more than one suppliers/drug, increase financial budget of oncology drugs for hospitals) | The government should encourage the pharmaceutical manufacturer to have more manufacturing plants and give some subsidiary support. They can encourage the pharmaceutical industries to produce a good number of anti-cancer drugs. Theyu can even export as well if they have some quality standard pharmaceutical manufacturing plants (P13). | |
National level drug shortage platform | There is also a need for a national-level drug shortage platform to tackle this situation (P5). | |
Manufacturers | Local manufacturing of quality anti-cancer drugs/APIs | The drug manufacturers can make a union so that they can ask lawmakers and the government, and pressurize them to make factories and produce raw material from our own country (Participant 22). |
Make a committee to deal with APIs shortages | Drug manufacturing companies should make some special type of team that deals with the active ingredient shortages and timely purchase (P15). | |
Distributors | Fair distribution(Avoid fake shortage) | Distributors cannot hold the stock on their own hands for their own benefits, but they’re doing it seriously. They should make it available for the patient, for the hospitals, for the other drugstores easily (P17). |
Minimize profit margin | Two things, the government should facilitate them, but at the same time, they should minimize the profit margin and ensure that those drugs are available in the market (P15). | |
Hospitals | Need of proactive measures (Generic prescribing in hospitals, admit patients/stock available, drug shortage platform, established role of pharmacist) | Brand deficiency can only be replaced with a generic prescribing (P15). |
There should be a proper drug shortage platform, committee, or type of drug product shortage team that also act as a help desk where pharmacist or doctor inform their complaint about drug shortages (P15). | ||
Shared Interventions among stakeholders | Anticipate and maintain a good inventory system | The hospital supply chain management or procure department should understand their needs and manage inventory accordingly (P10). |
Communication at the hospital level is very important | They should do agreements and contacts with distributors and other stakeholders to keep the drug flow. Other staff should corporate with each other to fix the solution of the medicine shortages (Participant 16). | |
Research surveys to get actual facts | The data available in Pakistan is too short or not available at any forum. There is no cancer registry platform at national level (P12). |
