The nearly three-hour meeting, held at a Warsaw hotel, was described by attendees as a session aimed at motivating and mobilizing party members ahead of what they called a crucial election.
Tusk, who leads the Civic Coalition, did not speak to reporters after the meeting, leaving the venue through a rear exit, state news agency PAP reported.
Deputy Education Minister Katarzyna Lubnauer said the gathering was intended to motivate lawmakers and give them an opportunity to raise questions directly to the prime minister.
"It was a motivational meeting," she told reporters.
Sports Minister Jakub Rutnicki said the coalition was focused on preparing for the election campaign.
"We have a very important election ahead of us," he said. "There were many good discussions, but above all we are mobilizing ourselves."
According to lawmakers who attended the meeting, Tusk warned about shifting political trends in Poland, including growing support for far-right parties, the rise of populism and increasing anti-Ukrainian sentiment.
He also stressed the need to adapt the party's political messaging, encouraging lawmakers to communicate more effectively through social media and use language that resonates with younger voters, according to the PAP report.
Lawmakers said the meeting also touched on a scandal involving Warsaw's Południowy Hospital, where state auditors recently identified widespread management failures and prosecutors are investigating allegations of fraud and abuse of office.
Lubnauer said the government supported healthcare reform proposals put forward by Health Minister Jolanta Sobierańska-Grenda in response to problems exposed at the hospital and elsewhere in the public healthcare system.
"What happened at Południowy Hospital, and what is happening in many hospitals, outrages us," she said. "The proposals put forward by Minister Sobierańska-Grenda are good ones, and we will implement them."
According to participants, Tusk also warned lawmakers to prepare for a "difficult political autumn," with possible protests by teachers despite pay raises introduced by his government.
He also urged party members not to accept opposition claims that the coalition had failed to hold the previous Law and Justice (PiS) government accountable, arguing that prosecutors were pursuing investigations involving an unprecedented number of former ministers.
One lawmaker who attended the meeting told PAP that he came away with the impression that the government was unlikely to pursue any major new reforms before the next parliamentary election.
Lower-house Speaker Włodzimierz Czarzasty warned last week that the ruling coalition risks losing the next parliamentary election unless it fixes problems in the country's healthcare system, calling the government's handling of the sector a major failure.
Tusk on July 3 demanded detailed proposals to address problems in the public healthcare system, warning that failure to act could result in dismissals.
Tusk, who served as president of the European Council from 2014 to 2019 before returning to Polish politics in 2021, led the Civic Coalition to victory in the 2023 parliamentary election, ending eight years of right-wing rule.
Poland's next parliamentary election is scheduled for the autumn of 2027, with right-wing and far-right parties seeking to return to power.
According to a recent survey by pollster CBOS, Tusk's Civic Coalition would win 25.1 percent of the vote if an election were held now, ahead of the opposition Law and Justice (PiS) party on 19.1 percent.
The far-right, economically liberal Confederation party would receive 15.2 percent, followed by the ultranationalist Confederation of the Polish Crown with 8.2 percent. Czarzasty's New Left party would win 5.3 percent, just above the threshold required to enter parliament.
