Effect of Clinical Pharmacist Consultation on Pain Management

During the study period, a total of 60 patients who had PM implantation surgeries will be recruited.

• Patients who had PM implantation surgeries in the Mabarra Heart Academy (MHA) will be randomly distributed into two groups using the sealed envelope randomization program: Control group : (30) patients will receive standard care for post pacemaker implantation surgery Intervention group : (30) patients will receive standard care for post PM implantation surgery plus clinical pharmacist consultation through direct interview on day 0 pre-discharge and by telephone on days 1 and 7 post discharge.
• On day 0 pre-discharge, patients' characteristics and medical history will be collected. In addition, patients' quality of life (QoL) will be assessed using European QoL 5-Dimentions 5-Levels version (EQ-5D-5L) - a Patient Reported Outcome (PRO) test that asks five questions to assess patients' overall quality of life, regardless of their medical problems- which contains a vertical EQ visual analog scale (EQ VAS, 0-100 points) and a descriptive EQ-5D-5L system. where the best possible health status is represented by an index value of 1, while the worst possible health state is represented by an index value of <0 . The instructions on how to fill the questionnaire will be explained to the patients and the questionnaire will be self-administered before the operation and two copies of the questionnaire will be given to them to be self-administered at home. Furthermore, pain scores will be assessed using numeric pain rating scale; patients will rate their pain on a scale from 0 to 10, where 0 indicates no pain and 10 indicates intolerable pain. All patients will be given a printed visual pain score to use to report their pain score daily.
• For both groups, pain scores will be reported daily via a WhatsApp message. In addition, on days 1 and 7, patients' QoL will be assessed as the researcher will remind the patients during the phone calls to fill the self-administered questionnaires at home on days 1 and 7. The photos of the answered questionnaires will be afterwards sent to the researcher via the WhatsApp application and the hardcopies will be collected from the patients later on day 10. Furthermore, the presence of any other side effects and the number of times they have contacted their physicians will be reported.
• For the intervention group on day 0; a 15-minute-consultation session with the clinical pharmacist will include detailed and personalized advice on how each patient should take his prescribed medications, the best time to take them, the possible drug-drug interactions, the possible adverse effects such as post operative nausea and vomiting (PONV), bleeding, fever and infection and the required action. A written paper outlining the main points including the detailed protocol with times and doses will be handed to the patient at the end of the consultation. Moreover, a recorded voice note with the detailed protocol will be sent to the patients via the WhatsApp application. They will be told that the researcher will contact them by telephone on days 1 and 7 to follow up with them and collect some information.
• For the control group on day 0; they will be told to contact their physician in case they have any questions or suffer from any adverse effects. They will be told that the researcher will contact them by telephone on days 1 and 7 to collect some information only.
• For the intervention group on day 1 and day 7 post-operation, direct communication by telephone will be conducted. Patients' adherence to their prescriptions will be assessed on a five-point scale where 5 = never, 4 = rarely, 3 = sometimes, 2 = often and 1 = always. Scores will be summed to give a total score, with higher scores indicating higher levels of reported adherence and they will be encouraged to adhere to their medications. Adverse effects will be recorded and recommendation on how to manage them -if present- will be explained. In addition, complications or signs of wound infection such as fever or redness or any other events related to the surgery will be reported and, in such case, patients will be advised to contact their physician.
• On day 10 post operation, a direct interview will be conducted for both groups to assess patients' outcomes in terms of pain severity, medication adherence by tablet counting method, the percentage of patients with unresolved side effects and wound infections, patients' QoL by the self-administered questionnaire, how many times they contacted their physician and the level of patients' satisfaction with medical services. Patient's satisfaction will be assessed using the short assessment of patients' satisfaction (SAPS) which is a seven questions survey with a score range of 0 to 28 where 0 indicates extremely dissatisfied and 28 indicates extremely satisfied
